The shootout in southern Paris on Thursday that left a policewoman dead and triggered searches of the area has not yet been linked with the attack on Charlie Hebdo, according to police sources.

Montrouge mayor Pierre Brossollette said the policewoman and a colleague went to the site to deal with a traffic accident. A car stopped and a man got out and shot at them before fleeing.

Witnesses said the shooter fled in a Renault Clio car. Police sources said he had been wearing a bullet-proof vest and had a handgun and assault rifle. However, one police officer at the scene tsaid the man did not appear to fit the bill of the Charlie Hebdo shooters.

French authorities are investigating a reported sighting of the two suspected gunmen - brothers Cherif Kouachi, 32 and Said Kouachi, 34 - at a Avia petrol station near Villers-Cotteret, in the north-east of France. The men were armed with guns and a rocket launcher, according to witnesses. It is feared the gunmen might be making their way back to Paris to carry out another assault or make a deadly final stand.

It comes as thousands of Parisians took to the streets for a minutes silence for the victims of the Charlie Habdo massacre. Hundreds held hands in central Paris in the pouring rain to honour those lost in the shooting.
